Title: Picture tube discharge device, leakage flux reduction method of picture tube and video device
Inventor: OGAWA SHIN
IPC: H04N3/16
Filed: 2000-07-05
Abstract: PROBLEM TO BE SOLVED: To reduce the magnetic flux leaking to the outside, without having to install a circuit for generating another magnetic field. SOLUTION: The picture tube discharge device comprises a deflecting coil, which generates a magnetic field for deflecting the electron beam of the picture tube, based on the drive current from the deflecting circuit and a transformer circuit, which is supplied with the drive current and comprises a coil that is wound in the direction, so as to cancel the leakage magnetic flux from the deflecting coil and supplies the high voltage to the picture tube. Since the flux leaking from the transformer circuit cancels the leakage flux from the deflecting coil, a shield material for covering the deflection coil or a circuit for generating another magnetic field is not required, the leakage flux from the deflecting coil can be reduced.

Title: Cable guide member, device cover and recorder
Inventor: TSUYAMA KAZUHIKO
IPC: B41J29/00
Filed: 2000-07-12
Abstract: PROBLEM TO BE SOLVED: To reduce or eliminate noise which may be generated by collision of a curved section of a flat cable with a guide member during the reciprocating movement of a recording section. SOLUTION: The curved section 6b of the flat cable 6 having one end fixed to a carriage 7 is changed in a bending condition during the reciprocating movement of the carriage 7. The curved section 6b tends to collide with the cable guide member 30 that restricts the change in the bending condition of the curved section 6b by the high speed movement of the carriage 7. However, a guide face 30b is formed on the cable guide member 30 such that it escapes in the collision direction of the curved section 6b so that the curved section 6b is gradually brought into contact with the guide face 30b, thereby suppressing occurrence of sound noise.
